Between 1990 and 1991, Wisconsin's bald eagle population grew dramatically in numbers of adult birds and active nesting territories. In 1991 and 1992, 414 active nests were known in the State, up from 358 in 1990. The number of young produced per nest is believed to be at or above the 1.0 level specified as a goal in the recovery plan. However, the amount of available habitat is decreasing because of resource extraction, construction, timber harvest, and highway expansion. Increased mortality and reduced productivity have been noted along the Great Lakes, probably the result of contaminants in prey. Additionally, eagles continue to suffer from electrocution, shooting, trapping, and intentional and accidental poisoning.
The National Park Service, Forest Service, and Wisconsin Department of Natural Resources have been involved in identifying and protecting bald eagle nest sites, making eagle counts, and conducting public education activities.
Permanent protection for eagle habitat will be needed if the species is to achieve full recovery. Also, additional study of reduced reproduction along the Great Lakes is needed, along with steps to solve any problems found. Public education to explain the species' comeback should be increased, with emphasis on the need for continuing conservation. Illegal killing and harassment of bald eagles should be investigated and prosecuted.
Wisconsin received $5,400 in FY 1991 for preparing wintering area management plans.
National Park Service and Forest Service: Both Federal agencies have incorporated bald eagle nest site identification, protection, and management activities into their land management plans. They also cooperate in eagle counts and public education activities.
Wisconsin Department of Natural Resources: In cooperation with Federal land management agencies, the Department conducts annual counts of bald eagle nest sites. The agency is also developing nest protection plans for all new nest sites, as well as guidelines for protecting and managing important bald eagle wintering areas. The "Adopt an Eagle Nest" program initiated by the Department has been highly successful in increasing public awareness of the eagle's status and has been a productive fund-raiser.
